SMQKJEl-CONSUMDVG DEVICE FOR HEATERS OR BOILERS.

Specification of Letters Patent.

Patented Aug. it, tutti Application filed October 1; 1913. Serial no. mama To all whom it may concern I Be it known that I, EDWARD C. HooK, a

, citizen of the United States, residing at Bufialo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Smoke-Consuming Devices for Heaters or Boilers, of which the following is a specification.

My invent1on relates to smoke consuming devices for heaters, boilers and furnaces, and it has for its object the provision of a device of this kind which can be easily attached to any heater, boiler or furnace and be so located with reference to the fuel in the fireplace that it will direct jets of heated air into the fireplace so as to commingle with the unconsumed products of combustion and cause said products to become ignited. Another object of my invention is to provide a smoke consuming device of this kind which will occupy a comparatively small space in the fireplace and which will not interfere with the feeding and will at the same time direct jets of heated air over an extended area.

-A further object is to provide a smoke consuming device of this kind which will be of simple and inexpensive construction and in which air is directed from the exterior of the heater, boiler or furnace to a. series of escape tubes.

'With these and other objects in view, the invention consists in the novel featuresof construction and in the arrangement and combination of parts tohe hereinafter described and more particularly pointed out in the subjoined claims.

In the drawings,Figure 1 is a perspec tive view of a heater or boiler showing the same equip ed with my improved smoke consuming evice and having a portion of its wall broken away to illustrate said device within the fireplace. Fig. 2 is a horizontal section through the smoke consuming device and that portion of the wall of the heater or boiler supporting the same.

Fig. 3 is a longitudinal section-taken on line 8-3 Fig. 2. Fig. 4: is a transverse section of one of the air escape or distrib uting tubes. Fi 5 is a central section through a modi ed form' of hot air distributer. Fig. 6 is a vertical longitudinal section through the inlet tube showing a modified construction.

of fuel thereinto Referring now to the drawings in detail, s1m1lar numerals of reference refer to similar arts in severalfigures.

T e reference 7 desi ates a heater or boiler having the usual replace 8, through the wall of which is passed an air inlet tube 9, said tube extending inwardly to a point near the center of the fireplace and having attached thereto an air distributor 10. Forming part of the air inlet tube is an in ector 11 inthe form of a casting, into the ends of which is threaded two sections 12, 13 of said inlet tube, said casting having an opening 14 in its bottom and a nozzle 15 centrally disposed therein and terminating at a point beyond said opening. The parts thus secured constitute the smoke consuming device. The air distributer 10, comprises a central portion 16 having a central opening 17 and an annular air passage 18.

A wall separating said central'opening from" said annular air passage is provided with a lurality of air escape openings 19 and pro ecting outwardly from said central portion are radiating distributor or air escape tubes 20, the outer ends of which are closed and which have near said outer ends air.

escape openings 21, said tubes being preferably of triangular sha e in cross section,

as shown in Fig 4, and t e air escape open-- ings therein being formed in the down-.

Wardly diverging walls of said tubes so as to cause the air from said tubes to be directed laterally and downwardly, whereby the jets of air are directed toward the fuel and over an extended area thereof. By thus directing the air jets from the radiating tubes they meet the rising unconsumed products of combustion and are thus thoroughly commingled therewith causing ignition of said products and complete consumption thereof.

It is to be noted that hot air from the fireplace enters the air inlet tube 9 through the opening 14 in the injector, and its entrance is accelerated by the exterior air escaping from the nozzle 15 in its passage there through. This hot air commingles with the exterior air in its passage through the inlet tube and distributer, and is furtherheated during such travel. The air escaping from the openings 19 in the wall separating the central opening of said distributor from the annular passage 18 therein commingles with any unconsumed products of combustion 1W passing through said central opening, and by constructingthe distributer as described the inrushing exterior air which is heated in its passage to and through the distributor is ejected from the latter over almost the entire area' of the burning fuel, assuring complete consumption of all gases and other un'consumed products escaping from the burning fuel.

distributer has a central chamber 22 into which the inlet tube 9. enters from the'bottom, the radiating distributer tubes 23 being in direct communicationwith said central chamber.

In the modification shown in F ig. 6 the inlettube is provided with a nozzle 24 at its inlet end, said nozzle being threaded or otherwise fastened thereinto, and a second nozzle 25 is located between said'first-mcntioned nozzle and the distribnten-Qsaid second nozzle having one end enlarged and directed downwardly to or through an opening formed said inlet tube. ,The air passing inwardly, through said inlet tube draws in the heated air from the firepla e while passing the end of said second nozzle,

said heated air thoroughly commingling with the exterior air and heating the same and said commingled air being further heated in its passage to and through the distributer.

Having thus described my invention, what I claim is,

a centrally located hollow annulus having air escape openings to direct the air to the axis of said annulus, horizontally-dis osed radial tubes connected to said annulus and having air escape openings, each of said tubes being of trlangular formation in cross section and arranged to provide two downwardly-diverging walls in which said last- "mentioned air escape openings are located,

In the modification shown in Fig. 5 the 1. A smoke consuming device comprising.

and an air inlet tube connected to saich centrally located annulus.

2. In a smoke consuming device adapted to be located in the fireplace of a heater, boiler or furnace, the combination of a distribntercomprisin a centrally-located hollow annulus and dial tubes extending from said annulus, said tubes an'd ahnulus having air escape openings, and an air inlet tubeconnected to said distributer and adapted to lead exterior air to the latter, said inlet tube having an open- 1 ing in the fireplace for the admission of hot air from the same, the hot air only being adapted to commingle with the exterior air in its f'assageto and through said distributer an the commingled bodies of air being adapted to be heated in their course to said air escape openings. i 3 v 3.In a smoke consuming device'adapted to be located in the fireplace of a'l1eater, boiler or furnace, the combination with distributor comprising a; centrally located" hollow annulus and horizontally-disposed orizontal1y-disposed,ra-

radial tubes extending from said annulus,

said tubes and annulus having airescape openings, an air inlet tube extending from the distributer and adapted to pass through the wall of the fireplace to admit exterior air thereto, and an injector connected to said air inlettube and comprising a casing having a centrally-disposed air nozzle through which only the exterior air is passed,

and an opening for the admission of hot air into the space surrounding said nozzle, the whole being arranged so that only hot air and exterior air commingle in their passage to the distributer.

In testimony whereof I afiix my signature in presence of two witnesses.
